Abstract
Background: Ecological models are currently the most used approaches to classify and conceptualise determinants
of sedentary behaviour, but these approaches are limited in their ability to capture the complexity of and interplay
between determinants. The aim of the project described here was to develop a transdisciplinary dynamic framework,
grounded in a system-based approach, for research on determinants of sedentary behaviour across the life span and
intervention and policy planning and evaluation.
Methods: A comprehensive concept mapping approach was used to develop the Systems Of Sedentary behaviours
(SOS) framework, involving four main phases: (1) preparation, (2) generation of statements, (3) structuring (sorting and
ranking), and (4) analysis and interpretation. The first two phases were undertaken between December 2013 and
February 2015 by the DEDIPAC KH team (DEterminants of DIet and Physical Activity Knowledge Hub). The last
two phases were completed during a two-day consensus meeting in June 2015.
